Po-Chih Leong's debut film was a trendsetter in Hong Kong cinema. Shot from the shoulder, the fast-moving world of cops, informers, drug dealers and other crooks are evoked in a very lively and realistic way. The action all takes place in carefully selected locations, among them the walled city of Kowloon and Yuen Long. The film looks like a documentary and evokes the kind of excitement usually seen in news programmes. The story focuses on the battle between two gangs and starts in Amsterdam, where one of the gang leaders is murdered.

Charlie Chan is a boxer who goes to Japan to take on a local hotshot in the ring. A gang of yakuzas pressure him to take a dive, but Charlie beats his opponent senseless instead, resulting in a life-or-death chase in which Charlie and his coach try to escape from the angry gangsters. They are spared by the yakuza boss Yakoda, and their eagerness to impress him leads them to pretend that they are the leaders of an influential triad organization known as the Marlboro Gang. That gang doesn't really exist, and their ruse only leads them to further endangerment after Yakoda is murdered by one of his employees. Yakoda's widow sends their daughter (who speaks Cantonese) to Hong Kong so that she won't be next on the hit list, and Charlie -- still pretending to be a powerful triad gangster -- agrees to protect her. He and his friends must save the girl from assassination attempts and kidnapping along the way, as well as coming to the rescue of Yakoda's widow.
